Future of Optical Coherence Tomography: Ultrahigh-Resolution Versus Standard-Resolution OCT
Optical coherence tomography (OCT) is a noninvasive technology that enables high-resolution cross-sectional imaging of tissue by measuring backscattered light.1 Optical coherence tomography imaging is analogous to ultrasound B-mode imaging but uses light instead of sound. By performing multiple longitudinal scans at different transverse locations, a two-dimensional (2D) scanned image is obtained. Noncontact, noninvasive human eye imaging using OCT proved to advance ophthalmic diagnostics by enabling direct cross-sectional retinal layer visualization and quantification.2
